Ohm's Law Calculator
Science - Physics - Electricity and Electric Current
The electrical relationships between resistance (R), current (I), power (P) and voltage (E) is defined by Ohm's Law. One ohm is defined as the resistance which allows
the current of one ampere under a potential difference of 1 volt.
